HENRY TETLOW, OF MANCHESTER, ENGLAND.

TRAVELER FOR RINGS OF RING-SPINNING AND DOUBLING FRAMES.

SPECIFICATION forming part of Letters Patent No. 631 ,342, dated August 22, 1899.

Application filed June 5, 1899. Serial No. 719,404. (No model.) 7

To all whom it ntay concern:

Be it known that I, HENRY TETLOW, heald and wire manufactu rer,a subject of the Queen of Great Britain and Ireland, residing at Varley street, Miles Platting, Manchester, in the county of Lancaster,England,have invented a certain new and useful Improvement in the Construction of Travelers for the Rings of Ring-Spinning and Doubling Frames, (for which I have made application in GreatBritain, No. 4,171, dated February 25, 1899,) of which the following is a specification.

My said invention relates to improvements in the construction of ring-travelers used to impart twist to the yarn in ring-spinning and doubling frames, as is well understood. These travelers are usually made from wire bent to a C or similar shape. It has been proposed, in order to obtain elasticity to spring the traveler on the ring and secure strength and ease of running of such travelers, to flatten the wire on two sides, the other two sides being rounded. When the wire is so bent to form the travelers that these rounded edges lie at right angles to the ring, a little less re sistance is offered to the atmosphere, while when the reverse disposition of the flat faces takes place and one rounded edge bears against the ring the friction between the ring and traveler is reduced.

My invention has for its object to produce a traveler which shall offer a minimum of resistance to the atmosphere and shall set up a minimum of friction by its contact with the ring and the yarn.

According to my invention I form the traveler from a section of wire having two faces, one perfectly flat and the other rounded or of a suitable convexity. When a traveler formed from wire of such plano-convex section is in use, the rounded or convex face bears against the ring, the flat face lying away from the rounded part a sets up little or no friction by its contact with ring represented by the line b,and the feather-edge 0, formed by the meeting of the outer flat face dand curved face (1, offers very little resistance to the atmosphere and is sensitive to the pull of the yarn, so that a traveler is produced which is in every way most suitable for the purpose. In addition a traveler constructed of wire of the indicated section will be found to be extremely strong transversely, while less breakage of the yarn occurs by reason of the rounded surface a, over which the yarn passes, not being liable to'cut the yarn as in cases where the traveler is flattened on both sides.

I declare that what I claim is 1. A traveler for ring-spinning and donbling machinery, havinga rounded inner face and a fiat outer face substantially as described.

2. A traveler for ring-spinning and donbling machinery having a rounded inner face and a flat outer face, said edges meeting on each side at an acute angle, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
